A look out towards Mauna Kea, which is another volcano of Hawaii. It is the tallest point in Hawaii, and home to numerous observatories (high altitude, close to the equator, and no light pollution). Mauna Kea is the tallest mountain on earth, measured from its base over 30,000 feet below sea level. It also is a dormant volcano, and is likely to one day send lava towards Hilo, on the east side of the mountain.
